Electrical connection spring, connector and electronic equipment

Abstract

The present invention discloses an electrically connected spring piece, a connector and an electronic device, wherein the electrically connected spring piece comprises a fixed part, an elastic part extends from one end of the fixed part, a through hole is provided on the elastic part, a conductive bead is provided in the through hole, and the conductive bead is used to rotate in the through hole. When the electrically connected spring piece is used in conjunction with a counterpart, the conductive bead is used to electrically contact the counterpart, and the conductive bead moves elastically with the elastic part. During use, since the conductive bead can rotate in the through hole, the contact position between the conductive bead and the counterpart is not fixed, which can reduce wear and dirt accumulation at the contact part, improve the electrical contact effect and durability of use. In addition, since the conductive bead and the elastic part are not formed in one piece, the conductive bead and the elastic part can be selected separately, so that the conductive bead can be selected from a material with higher strength, thereby further improving the durability of the product.

Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to an electrical connection spring, a connector and an electronic device. Background Art

[0002] With the advancement of science and technology and the development of the economy, electronic devices such as mobile phones and tablets have become indispensable daily necessities for people. These digital electronic products have been widely integrated into people's daily lives, providing great convenience for people's lives and work and enriching people's lives. Shrapnel is one of the indispensable devices in electronic devices.

[0003] Several springs are set on each connector in electronic devices, and the springs are used to connect the circuits or devices on both sides of the springs. With the trend of miniaturization of electronic devices in recent years, the internal connectors of the devices are also miniaturized. The existing spring application is to set the spring connector on one side of the substrate, and set the contact surface of the other substrate to contact the spring to achieve the purpose of crimping connection.

[0004] However, the existing spring piece realizes electrical contact by setting a convex bump in the spring piece, and the contact position of the convex bump with the counterpart is fixed. After long-term use, the convex bump is easy to wear or accumulate dirt, thereby affecting the electrical contact effect. In addition, because the convex bump and the elastic part of the spring piece are integrally formed, the material selection of the convex bump is limited, and high-strength materials cannot be selected. Summary of the invention

[0005] One purpose of the present invention is to propose an electrical connection spring to solve the problem in the prior art that the contact position of the convex bulge is fixed, and after long-term use, the convex bulge is easily worn or dirt accumulates, thereby affecting the electrical contact effect, and the material selection of the convex bulge is limited and high-strength materials cannot be selected.

[0006] An electrically connecting spring piece comprises a fixing portion, one end of which extends an elastic portion, the elastic portion is provided with a through hole, the through hole is provided with a conductive bead, the conductive bead is used to rotate in the through hole, when the electrically connecting spring piece is used in conjunction with a counterpart, the conductive bead is used to electrically contact the counterpart, and the conductive bead moves elastically with the elastic portion.

[0007] According to the electrical connection spring sheet proposed in the present invention, an elastic part extends from one end of the fixed part, a through hole is provided on the elastic part, and a conductive bead is provided in the through hole. When the electrical connection spring sheet is used in conjunction with the counterpart, the conductive bead is used to electrically contact the counterpart, and the conductive bead performs elastic movement with the elastic part. During use, since the conductive bead can rotate in the through hole, the contact position between the conductive bead and the counterpart is not fixed, which can reduce wear and dirt accumulation at the contact part, and improve the electrical contact effect and durability of use. In addition, in traditional electrical connection spring sheets, since the elastic part is limited by the requirements of elastic deformation and conductivity, only specific elastic conductive materials can be selected, and the requirements of high strength and elasticity cannot be taken into account. In the present application, since the conductive bead and the elastic part are not formed as one piece, the conductive bead and the elastic part can be selected separately, so that the conductive bead can be selected from a material with higher strength, thereby further improving the durability of the product.

[0008] In addition, the electrical connection spring provided by the present invention may also have the following additional technical features:

[0009] Further, the fixing portion includes a main body portion, and the elastic portion and the welding portion are respectively extended from both ends of the main body portion along the first direction, the elastic portion includes an elastic main body, and the first protection portion and the second protection portion are respectively extended from both ends of the main body portion along the second direction, and the first elastic portion and the second elastic portion are sequentially extended from one end of the elastic main body portion away from the main body portion, the first elastic portion and the second elastic portion form a U-shaped structure, the through hole is arranged on the first elastic portion, and the conductive bead is in contact with the second elastic portion.

[0010] Furthermore, a limiting hole is provided on the second elastic portion, and the bottom of the conductive bead is arranged in the limiting hole.

[0011] Furthermore, the diameter of the limiting hole is smaller than the diameter of the conductive bead.

[0012] Further, the first protecting portion extends a first limiting portion toward the second protecting portion, the second protecting portion extends a second limiting portion toward the first protecting portion, the second elastic portion extends a buckle portion away from one end of the first elastic portion, the first limiting portion and the second limiting portion are in contact with the buckle portion respectively, and the buckle portion is located in a space enclosed by the main body, the first protecting portion, the second protecting portion, the first limiting portion and the second limiting portion.

[0013] Furthermore, the buckling portion is arranged parallel to the main body.

[0014] Furthermore, welding feet are provided at the bottom of the welding portion, the bottom of the first protecting portion, and the bottom of the second protecting portion.

[0015] Furthermore, a limiting platform is extended from one end of the first protecting portion away from the welding leg toward the second protecting portion, and the connecting portion is located between the limiting platform and the welding leg.

Several embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] See also Figures 1 to 4 The electrical connection spring sheet proposed in the first embodiment of the present invention includes a fixing portion 100, an elastic portion 200 extending from one end of the fixing portion 100, a through hole 511 is provided on the elastic portion 200, a conductive bead 60 is provided in the through hole 511, and the conductive bead 60 is used to rotate in the through hole 511. When the electrical connection spring sheet is used in conjunction with a counterpart, the conductive bead 60 is used to electrically contact the counterpart, and the conductive bead 60 follows the elastic portion 200 to perform elastic movement.

[0028] Specifically, the fixing portion 100 includes a main body portion 10 , and the elastic portion 200 and the welding portion 30 are respectively extended from two ends of the main body portion 10 along the first direction.

[0029] Specifically, the elastic part 200 includes an elastic main body 20 , and the angle between the elastic main body 20 and the main body 10 is an acute angle.

[0030] Preferably, a hollow portion 101 is provided on the main body 10 to reduce weight.

[0031] A first protection portion 41 and a second protection portion 42 are respectively extended from two ends of the main body 10 along a second direction. Specifically, the first direction is perpendicular to the second direction.

[0032] A first elastic portion 51 and a second elastic portion 52 are sequentially extended from one end of the elastic main body 20 away from the main body 10 , and the first elastic portion 51 and the second elastic portion 52 form a U-shaped structure.

[0033] The through hole 511 is disposed on the first elastic portion 51, and the conductive bead 60 is in contact with the second elastic portion 52. Specifically, the conductive bead 60 can be a copper bead or a conductive ceramic bead with relatively high strength.

[0034] In this embodiment, a limiting hole 521 is formed on the second elastic portion 52 , and the bottom of the conductive bead 60 is disposed in the limiting hole 521 .

[0035] Specifically, the diameter of the limiting hole 521 is smaller than the diameter of the conductive bead 60. The conductive bead 60 is limited by the limiting hole 521.

[0036] The first protecting portion 41 extends a first limiting portion 411 toward the second protecting portion 42, the second protecting portion 42 extends a second limiting portion 421 toward the first protecting portion 41, the second elastic portion 52 extends a buckling portion 53 at one end away from the first elastic portion 51, the first limiting portion 411 and the second limiting portion 421 are in contact with the buckling portion 53 respectively, and the buckling portion 53 is located in a space enclosed by the main body 10, the first protecting portion 41, the second protecting portion 42, the first limiting portion 411 and the second limiting portion 421.

[0037] In this embodiment, the buckling portion 53 is arranged parallel to the main body 10 .

[0038] The bottom of the welding portion 30 , the bottom of the first protection portion 41 , and the bottom of the second protection portion 42 are all provided with welding feet 70 for achieving welding.

[0039] In this embodiment, a limiting platform 80 is extended from one end of the first protecting portion 41 away from the welding foot 70 toward the second protecting portion 42 , and the elastic main body 20 is located between the limiting platform 80 and the welding foot 70 .

[0040] According to the above-mentioned electrical connection spring piece, an elastic part 200 extends from one end of the fixed part 100, and a through hole 511 is provided on the elastic part 200, and a conductive bead 60 is provided in the through hole 511. When the electrical connection spring piece is used in conjunction with the counterpart, the conductive bead 60 is used to electrically contact the counterpart, and the conductive bead 60 follows the elastic part 200 to perform elastic movement. During use, since the conductive bead 60 can rotate in the through hole 511, the contact position of the conductive bead 60 with the counterpart is not fixed, which can reduce the wear and dirt accumulation of the contact part, and improve the electrical contact effect and durability of use. In addition, in traditional electrical connection springs, since the elastic part is limited by the requirements of elastic deformation and conductivity, only specific elastic conductive materials can be selected, and the requirements of high strength and elasticity cannot be taken into account. In the present application, since the conductive bead 60 and the elastic part 200 are not formed as one piece, the conductive bead 60 and the elastic part 200 can be selected separately, so that the conductive bead 60 can select a material with higher strength, thereby further improving the durability of the product.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
